[pytest-dev] Testing of console scripts

[Vasily Kuznetsov]

Thanks for the pointers, Florian.

The testdir fixture from pytest is pretty much what I was thinking about.
So if we could have a more generic version of it, wouldn't it be cool?

pytest-cram and cram in general looks quite neat, but I guess it doesn't
allow the second approach of running everything in the same python process,
which is an important feature for example for doing TDD.
